"caffe_unet was not found"

[wlynn53545354]

Hi there,

I hope you are well! I am trying to run the U-Net plugin (not on a remote server). I followed the video instructions here (https://lmb.informatik.uni-freiburg.de/resources/opensource/unet/#troubleshooting) to open the plugin, and to set the directory for the caffemodel. When I try to run it, it gives me an error message saying "caffe_unet was not found." The Log contains an error message "java.io.IOException: Cannot run program "caffe_unet":error=2, No such file or directory." Please see screenshots for more info! Thanks in advance for your assistance!

Best,
Wei

Hi Wei,

There may be different reasons. Basically the caffe_unet binary is the backend that is used by the plugin. The plugin assumes caffe_unet is installed and its path is added to the PATH environment variable. If it is not, the plugin asks for the path caffe_unet is installed to.

1. Ensure caffe_unet is installed and can be executed from a shell environment.

• Open a shell and type caffe_unet
  • Usage message (may look like an error message on the first glance) appears, then you are fine
  • No such file or directory... your PATH environment variable must be setup to point to the caffe_unet installation path (the folder containing the caffe_unet binary). If you set the PATH in .bashrc, ensure that .profile sources .bashrc.
  • Symbol xxxyyy not found in libcaffe.so.0: you have a system-wide caffe installation from your OS, ideally you simply remove it, if this is no option you need to write a small setup script that sets the LD_LIBRARY_PATH environment variable to give the libcaffe.so.0 from caffe_unet precedence over the system libcaffe.so and source this setup script before starting caffe_unet/Fiji.

2. Start Fiji in the shell environment you could successfully run caffe_unet from

If starting Fiji via double-click in your WindowManager you must find out how to persistently set environment variables for your WindowManager. There is no single solution that works for all.

Hello, I also have the same caffe-unet not found problem, I am running the imagej plugin on the windows system, see you said that this plugin needs a front-end and a back-end server to run, does the back-end server need to connect through the use remote host by default, or can it be deployed locally, because I am a foreign school personnel, I don't know how to apply for an account and use the remote connection, if I want to deploy locally, how to proceed, Expect to hear from you!
